Abstract
A press pad is provided for use in a laminate press operating at temperatures of up to 180.degree. C. such as a high pressure laminate press or a veneer or marquetry press. The pad includes a woven fabric of strands that are heat resistant up to 200.degree. C. and wherein a substantial proportion of at least one of the warp and the weft includes silicone covered strands. The fabric contains no metal strands and the other of the silicone covered strands includes at least one of a polyester and a non-aromatic polyamide yarn, such as nylon. Preferably, the silicone covered strands include a silicone covered glass yarn. The weight of such a pad can be made less than one third the weight of a conventional press pad containing a substantial proportion of metal wires, which facilitates the handling and manipulation of large press pads by press operatives. In addition, it is inexpensive to produce.
